Abstract
The power supply system for a DC powered electrical transit system is adapted to accommodate normal, surge and continuous peak demands by locating battery equipped secondary power supplies at locations which create excess power demands such as at passenger stations, at the beginning of an uphill grade and at midpoints between the primary power supplies. During normal operation, the batteries are charged and during surge or peak demand periods, are discharged to provide additional power to the system.
